A worldwide leader in the production of hip stems, Marle also has extensive experience in industrializing instruments for orthopedic surgery. The Marle teams regularly develop proprietary manufacturing techniques, which improve ergonomics and operating effectiveness of instruments and insertion ancillaries.
Marle has developed a handle-broach coupling technology now available for arthroplastic hip surgeries, which meets the needs of minimally invasive approaches. This technology is available for specific anterior as well as posterior instrumentation.
Patented in France and currently pending international extension, this technology can be mobilized for many orthopedic instrumentation projects.
Compensates by 100% the mechanical play between handle and broach
This technology completely compensates any play between the broach handle and the broach body, thanks to an innovative system that transmits the surgeon's manual effort and movement between the trigger and the locking system. The play resulting from wear of the contact components is also gradually compensated.
Thanks to this garanteed total absence of play, the surgeon can very quickly and carefully evaluate the stability of the broach within the femur, even in case of wear of the contact surfaces.
Technology suitable for minimally invasive approaches
This technology is based on a female connecting system on the broach and male on the handle especially suitable for minimally invasive surgeries. Following the removal of the broach handle, the surgeon has plenty of space to prepare the acetabular cavity.
The broach handle is available in different designs and allows the practice of minimally invasive approaches, in order to preserve the muscular system and thus reduce postoperative recovery time.
During surgery, the coupling of the broach with the handle is very intuitive and alignment of the bores and axes of the two bodies is accomplished almost automatically: a major advantage in minimally invasive approaches where visual control is very partial.
Possible adaptation for all types of implant
This technology is suitable for any type of implant and instrumentation, and even for reworking and retrofitting by machining.
